NPE in KeyValueClient.getValuesAsString()

[lbertrand]

If this method is called with a non existing key, a NPE is thrown, instead of the method returning an empty list

Simple unit test

public class SimpleTest {
    @Test
    public void testNPE() {
        Consul consul = Consul.newClient();
        List<String> shouldBeEmpty = consul.keyValueClient().getValuesAsString("unknownKey");
        assertTrue(shouldBeEmpty.isEmpty());     
    }
}

Thanks for providing a unit test. I'll see if I can get to this next week.
